The message is only on screen briefly, but I think the first line says something about 'NETWORK DISCOVERY SERVICE DISABLED'. It goes on to say my choice is incompatible with ...Avahi something, and it is not recommended. If I power off BOINC and power on the Ubuntu Linux VM I unnecessarily created I get the same message. And under Network in both cases it mentions Bridged Adapter, Broadcom NetLink (TM) Gigabit Ethernet Adapter, which is the host Ethernet adapter. And during setup, of all the choices, there was only one that brought up any mention of the physical host adapter.

How can I find out if I have network connectivity. It looks like I do, because of the flashing red and green lights by the 4th icon from the left at the bottom of the screen. But the error message doesn't seem like something that can be ignored.
